EZ-Flash IV (microSD) has corrupted save data on SMA1.

I have the latest kernel, and there's no save file on the microSD Card. Loading SMA1 from NOR doesn't help. Is there some way to maybe erase any saved data that SMA1 may be trying to access?
Edit: Just to clarify, i'm using the No-Intro (USA, Australia) Dump of Super Mario Advance 1
